पास्कल पहचान के अनुसार \(\binom{5}{2}+\binom{5}{3}\) किसके बराबर है?
By Pascal's identity, \(\binom{5}{2}+\binom{5}{3}\) is equal to which expression?
Explanation opens after your attempt
Correct Answer
A. \(\binom{6}{3}\)
Concept
Pascal's identity is \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{6}{3}\).
Why this answer is correct
The correct answer is A. \(\binom{6}{3}\). Pascal's identity is \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\). Hence the answer is \(\binom{6}{3}\).
Exam Tip
पास्कल पहचान \(\binom{n}{r}+\binom{n}{r+1}=\binom{n+1}{r+1}\) है। इसलिए उत्तर \(\binom{6}{3}\) है।
